I think there is a wide variety of outcomes in this situation (breastfeeding after breast surgery). As you probably already know, it is possible to have a full supply and breastfeed only on one side, so that is not necessarily an issue.
You've probably already found this, but here are some LLL articles:
Here is some more information:
Can you breastfeed with implants?
Breast feeding with breast implants is easier than breastfeeding after a breast reduction because the breast tissue is still intact. Implants that are inserted through a periareolar incision “through the nipple area” are more likely to cause problems for breastfeeding.
I have found Livestrong to have fairly good information in the past:
The rumor mill is packed with ideas about a woman's ability to breastfeed after implants. The truth is, many women are still able to do it. There may, however, be problems or complications that limit a woman's ability to breastfeed. A study published in the Annals of Plastic Surgery in 2010 found a 25 percent decrease in breastfeeding ability in women who recently had implants when compared to a control group. Some of these women were able to breastfeed but had to supplement with formula. A study at Texas Children's Hospital reported by the National Research Center for Women and Families found 67 percent of women had an insufficient milk supply.
Having breast augmentation surgery carries with it a few common side effects. One of these that perhaps has the largest affect on breastfeeding is loss of nipple sensitivity, according to the National Research Center for Women and Families. Women with no feeling in their nipples might have difficulty with their latches and their bodies might miss many of the signals for their breasts to make more milk. If a woman has a significant amount of breast tissue removed before implants, the milk glands could be damaged or removed. Surgical scars, size of the implant, infections and surgical complications can also affect breastfeeding.

While you can't be positive about your personal outcome, you probably do have some information that will be indicative of how likely you are to be successful. Do you know if your nipple was removed/moved during surgery? Do you still have significant sensation on that areola?
This site also seemed to have some good info:
According to that site, pregnancy actually quickens the rate your body is trying to "regrow" milk production ability. That said, they also say that it can take up to five years.
